GO, ILLINOIS, ASSIGNOR, BY MESNE ASSIGNMENTS, TO

MILWAUKEE, WISCONSIN, A CORPORATION LOCK SWITCH.

Application filed May 2, 1923. Serial No. 636,164.

This invention has for its object vide a lool; switch suitabl trolling the lignting or aiiti-oir.chiles.y or beth various locking O if but servo-s te electricalli7 other purposes. and in which operation not a venting the operation ot' the to proe 'for use in coniition circuits ot their.. and

n'ieaiis for preitch handle prevent the performance ot the switching functions controlled ny such handle,

Another object of the in vide such a switch as a compi and ignition switch vhire mechanism has two lockedx unlocked position and in vention is to proation liggjhtingi the hacking 3i Vion-s and one olE its loclied positions and in its unlocked position it serves to complete the circuit to the 1iigl g switch and in its unlocked position it sei to render etiective an ignition circuit, while in its other locked positie n it serves to in terrugt the circuit to the lighting switch and render the ignition circuit ineffective.

is a sectional viewv of the front plate with the locking sleeve attached. and

Fig. 13 is a detail view detent member.

ot' the stationary 1n these drawings, 15 indicates a front plate to which is secured a case 16 having an insulati 17 secured to its end.

cylindrical switch ng terminal head A lighting switch handle 18 on the iti-ont of plate 15 operates an insulating switch member 19 on the hack of the plate. having connection therewith through arc-shaped slots 20. vA Contact spider 21 carried bysaid insulating switch member 19 has its projecting contact fingers bearing en the terminal head to engage an outer series ot contact studs thereof for controlling lighting` ein cuits, the various positions of the switch handle for such control being indicated on the front plate. Y

Passing through an opening in the tron-t. plate and through an opening in the handle is a lock barrel 23 having a slot to receive a key 2A to withdraw its tumblers Q5 trom engagement with openings in a stationariy lock sleeve 26 so as te permit said lock barrel to be turned by means ot the hey. Th, lock sleeve is anchored to the liront plate by having a flange at its end slit radially7 to form projections which alternately engage above and below the bent edge ot the opening of the :tront plate and are embedded therein by pressure so as to secureli7 hold the lock sleeve in place against rotation.

A flange 27 on the lock barrel contained in the space between the bent edge oit the front plate opening and the switch ineinlierV 19 forms a stop for limiting the movements of the lock barrel by engaging its ends with an inturned lug QS on said edge ot the Ytrent plate opening.

The inner end of the loch barrel is recessed to receive a coiled spring .29 and is slotted to form two arc-shaped projections 3() wl .ch lit in correspondingly shaped openin in iin insulating switch member 31 carryingy contact ring 32 with projection-s to .tit an inner series of contact studs in the terminal head.

To give the lighting switch handle a more decided detent action than is ailorded bv the engageinent'ot the fingers ot the contact spider 21, with the recessed contact studs. a U-shaped spring member 33 is secured to the switch member 19 hy the screws 34 which connect it with the handle. and an angular bend in the center of said spring is adapter to engage in similar detent bends in :in arched stationary member 35 fastened to the switch case. y

The contact studs in the terminal head form binding posts in the usual manner which are marked on the terminal head intti i dicating` the circuit wires to be connected therewith and it will be seen that, while the outer series oit studs for the lighting circuits are marked for the various ligiting connections such as Sin-all heads, Large heads and Rear, it does not contain a. battery stud with this switch construction, the hat.; connection et the lighting switch is derived from the ignition switch. However, there is a Contact stud 3G in this outer series, which is connected by a nietal strip 37 with two studs 38 39 oi' the inner series. The other contact studs lo and lll oia the in" series are marked Battery and Llonition respectively, and the conne@ tions l; tween theni in the various positions of the lock h '"el are shown in nigs. 9, l0 and il, wherein Fig. 9 indicates one locked 'tion in which no Contact point oie the contact 32 enga l"he battery stud l0 and consequently the ignition is ineiiective and the lighting switch is inoperative for establishin any of the lighting circuits since it ha no battery connection. in Fig. l is shown the unlocked position in which the contact points oit the contact ring en- 1aire the ha. i stud i0 and the ignition stud fil, reno g' the :ignition eilte tive, and also stud 3?, which, by reason of strap coiniiection with stu y. fl ot the outer series, ,h a bat-y v connection for the n l "l n u witch so that it becomes operative. shown the other locking position in i the points oi the contact ring 32 connect with the battery stud fi() and stud 38, thus retaining battery connection tor the lightii o' switch but without connecting with trie igion stud so that the ignition circuit is ineffective.

reni these connections it will be seen that in the two extreme positions oi' the lock hai-rel in which the key may be removed, as indicated in Figs. 9 and ll, ignitioii is ineiltective and the engine inay not be operated, Vwhile in one position, llt-Vig. 9, the lighting switch is also inei'liective, having no battery connection, though in the othf position, F13'. ll, the lighting switch is effective, permitting ot the lighting arrangement being change lin the unlocked position, Fig. i0., the ig itionV is eifectiveand the lighting switch is operative.

This enables the switch to be locked so as to prevent theft ot the automobile either with or without the lighting` switch being locked in the sense that it is rendered ineffective.

switch mechanism for any purpose whether controlling one or more circuits.

i ,cease-1.

TN hat I claim as new and desire to secure by Letters Patent is:

l. A combination switch comprising a front plate. a switch handle mounted thereon, a switch nieniber .behind the front plate connected with the handle to be turned thereby, a. contact spider carriedV by the switch rneniber, a lock barrel mounted to turn in the switch handle, .a stationary lock sleeve engaged by the tuinblers ot the lock barrel, said lock barrel passing through the switch nien'iber, a spring-pressed switch ineinber carried by the lock barrel and having contacts, a terminal head having contact studs engaged by said cont-acts and the contact spider, there being connection between the contact stuls for the two switch ineinbers whereby they interlock.

2. combination lighting and ignition switch comprising lighting switch having ar handle, a lock nielnber having an unlocked position and two locked positions, an il iition switch operated by the lock nienibei .ith a Contact connected with a contact oi the lighting switch and arranged to establish battery connection for the lighting switch vin the unlocked positionand one locked position ot the lock ineniber and to close the ignition circuit only in the unlocked position of the lock member.

3. in a combination lighting and ignition switch capable ot being locked either with ignition ineffective or ignition and lighting ineffective consisting oit a lighting' switch having a handle, a lock nieniber therein havingan unlocked position and two locked positions, a battery connection and an ignition connection and a lighting switch connection controlled by the lock member, and a. lighting circuit connection controlled by the lighting switch.

5. ln a switch, a switch case, a switch nieniber mounted to turn therein, an arched sheet metal detent strip secured to the switch case and proifided with a wave-like surface forming detente, and a U-shaped spring n'ieinber secured to the switch inenil er and provided with an indentation to ride on the detent nieinber and engage the indentations thereof for providing yielding` stops or detents for `the operativel positions of the switch member. c
